CARIBURETER.

Specification of Letters Patent.

Application filed March 16, 1910. Serial No. 549,696.

To all 1/2/10"). it may camera:

Be it known that I, Svnxn ()nsnx, a subject of the King of Denmark,residing at .llalle, German Empire. have invented certain .new anduseful Improvements in Carburcters, of which the following is aspecification.

My invention relates to carbureters wherein liquid fuel is transformedinto a vaporous mixture, which is then fed to the place where the gas isrequired for use; arid the invention has reference in particular to thattype in which, for the purpose of securing ample surface for evaporationot the carbureting liquid. a 'aporizing passage of tortuous form.

is located in a relatively tlat structure tur nished with a cover. Adefect attaching to this Construction is that in the process ofpreparing the gas certain residual products collect in the vaporizingchannel and in the course of time choke up the passage. To remove theobstruction the entire apparatus has to be taken apart, which is notonly exceedingly troublesome, but necessitates complete stoppage of workfor a considerable period.

The present invention contemplates the removal-ct these drawbacks by soorganizing the parts that. access can be had to the vaporizing passagefor cleaning purposes without the inlet. and outlet pipes having to bedisconnected.

A practical embodiment of my invention is illustrz'ited in theacconipartying drawing, in whieh-- Figure 1 is a vertical section, andFig.2 a horizontal section on the line A- B, Fig. 1.

The carbureter comprises two main sec tions, viz. a lower tlat-shapedpart (I in which the vaporizing passage 7) is t'm-med, and a superposedpart c constituting a detachable cover.

l preter to give the vaporizing mssagc a spiral instead ot the usualzig-zag shape, as there is then. for the same cross sectional area, lessresistance oll'cred to the air. The passage may be advantageouslyconstructed in such manner that the base gradually descends as it.approaches the center of the ap para tus. 7

The cover 0 is furnished with a dome or cap (Z. which constitutes amixing chamber. and the. two sections a and communicate tlirt-niggdi:rniixingoipe c. for the supply of l ne], while air is admitted l l l ll t f is the inlet pipe thrtulgb the pipe 5 1/1 is the exit. throughwhich the gaseous mixture is fed to the. place of consumption.

To enable ready access to the vaporizing passage l for the purposeotcleaning it, t provide the inlets f and 1 and the outlet in, in thelower section a of the carblu'eter, the conuuunication between the cap(I and the outlet. in being ettected b means of a channel l.

The fuel in the passage 1) and the gaseous mixture in the cap (I may besubjected to heat with the aid of an annular chambeni, having connectingpipes l', located in the section (.1, and heated by any suitable source,for instance, in the case of motors, by the exhaust gases.

The lower part 11, with the passage and chamber [,may suitably be acasting, as the rough inner walls promote evaporation.

A. collector I) may be furnished for the residual products.

Having thus described my invention, I declare that what I claim as newand desire to secure by Letters latent of the United States is-- 1. Acarluireter, conlprising a lint-shaped section presenting a tortuousvaporizing-pas sagestirel and air inlets. and a gas outlet; atsuperposed detachable section having a mixlug-ca p. and a passagecommunicating with said gas outlet; and a pipe eonducting'from the lowersection into said cap; substantially as described' 2. A carbureter,comprising a tlat-shaped section presenting a spiral vaporizing-passage,fuel and air inlets. and a gas outlet: a superposed detacluible sectionhaving a mixing-cap, and a passage con'nnunicating with said gas outlet;and a pipe emnlucting trout the lower section into said cap;substantially as described.

3. carbureter, comprising a flat-shaped section presenting a tortuous.vaporizirig-passage. l'uel and air inlets, and a gas outlet, and havingan annular heating-chamber below said vaporizingpassage; a. superposeddetachable section having a mixing-cap. and a passage communicating withsaid gas out let; and a pipe conducting from the lower section into saidcap; substantially as described.
